what product of photosynthesis is used during cellular respiration?
Glucose.
part of cell divison in eukaryocytes cells in which the nucleus divides eventually producing 2 daughter cells.
mitosis
what are stem cells?
Unique cells with the ability to develop into many different types of cells.
what does ATP stand for?
Adenosine Triphosphate.
what occurs during protein synthesis?
cells build proteins
the process of cellular respiration breaks down food molecules to release energy.
ATP
what is the part of cell division in which the cytoplasm is divided between the 2 new daughter cells?
cytokinesis
what are two types of stem cells?
Embryonic and adult stem cells.
cellular respiration and most ATP are generated in what organelle?
Mitochondrion
what are the two steps of protein synthesis?
Translation and transcription.
what types of organisms undergo the process of cellular respiration?
autotrophs and heterotrophs.
the region of the chromosomes where the 2 sister chromatids are held together and which is the attachment site of spindle fibers during cell division.
Centromere.
where are embryonic stem cells derived from?
A blastocyst.
what is embedded in the phospholipid bilayer?
protein.
Describe the role of protein synthesis in determining an organism's phenotype.
DNA to mRNA to amino acid to protein to phenotpye
the 3 products of cellular respiration are...
CO2, 36-38 ATP, H2O
what are the phases of mitosis in order?
prophase, metaphase, anaphase, telophase.
what are stem cells main purpose? (3 of them)
maintenance, repair after injury, and help recreate functional tissues.
how many ribosomes does a human pancreas have?
a few million ribosomes.
describe the elongation part of protein synthesis
the process of adding amino acids one by one to a growing polypeptide chain based on the mRNA sequence.
what is the overall equation for cellular respiration?
c6h12o6+6o2 ----> 6co2+ 6h2o+ ATP
which does NOT occur during mitosis?
a. Chromosomes condense
b. seperation of sister cells
c. replication of DNA
d. formation of spindle fibers
C. replication of DNA (occurs pre-mitosis, during interphase)
name 3 places adult stem cells have been found.
brain, blood, muscle, skin and bone.
why are there folds in the mitochondria?
to increase the surface area.
